The generation of coherent Terahertz (THz) radiation is studied which is produced from moving the relativistic electron beam through a helical wiggler with axial magnetic field. The relativistic electron beam is modulated via interacts with the beat wave of two laser beams that have frequency difference in THz range. When the modulated relativistic beam of electrons go through the helical wiggler with axial magnetic field, it radiates coherent THz electromagnetic wave as an antenna. In addition, the numerical study has shown the maximum THz power increases with the increasing axial magnetic field power.
